Watts Bar Nuclear Plant, Unit 2 NRC Docket No. 50-391

Subject: ADDITIONAL INFORMATION IN SUPPORT OF TVA FINAL SUPPLEMENTAL ENVIRONMENTAL IMPACT STATEMENT (FSEIS) (TAC MD8303)

References: 1. TVA letter dated February 15, 2008, ' (WBN) - Unit 2 - Final Supplemental Environmental Impact Statement for the Completion and Operation of Unit 2"

2. TVA letter dated July 2, 2008, "Watts Bar Nuclear Plant (WBN) - Unit 2 - Final Supplemental Environmental Impact Statement - Request for Additional Information (TAC No. MD8203)"

3. TVA letter dated January 27, 2009, 'Watts Bar Nuclear Plant (WBN) Unit 2 - Final Supplemental Environmental Impact Statement - Severe Accident Management Alternatives (TAC No. MD8203)"

The purpose of this letter is to provide additional information in support of TVA's FSEIS for the completion and operation of WBN Unit 2 as requested by NRC during a site assessment in early October 2009.

Printed on recycled paper U.S. Nuclear Regulatory Commission Page 2 October 22, 2009

The WBN Unit 2 FSEIS (June 2007) was submitted to NRC on February 15, 2008 (Reference 1). -By letter dated July 2, 2008 (Reference 2), TVA responded to an NRC request for additional information. By letter dated January 27, 2009 (Reference 3), TVA provided the Severe Accident Management Alternatives (SAMA) analysis report for WBN Unit 2.

TVA prepared the FSEIS to update the extensive previous environmental record. The environmental consequences of constructing and operating WBN were addressed comprehensively in the 1972 Final Environmental Statement for WBN Units 1 and 2. The FSEIS summarized the environmental effects assessed in past WBN-related environmental reviews and assessed the potential for new or additional effects that could result from the completion and operation of WBN Unit 2. Some of the literature cited in the 2007 FSEIS consisted of historical studies performed by or for TVA to assess environmental conditions in and near WBN that are not available to the public. These studies are enclosed electronically.

During the site assessment, NRC also requested specific TVA procedures, additional site meteorological data and the Shapefiles used by TVA. These are also enclosed electronically. Enclosure 1 provides a listing of the documents attached in electronic format. There are no new actions required for licensing provided in this letter.

If you have any questions, please contact me at (423) 365-2351.

Sincerely,

Masoud Baj ni
